Advisory Fee Billing Reconciliation Automation for RIAs: A Quarterly Tie-Out Checklist

How do RIAs reconcile advisory fee billing?

RIAs reconcile advisory fee billing by comparing three things for each account, every cycle: the fee the billing platform calculated, the amount the custodian actually debited, and what the signed fee schedule or agreement allows. The check is independent on purpose: it doesn't just confirm the platform agrees with itself.

That check matters because of how the billing itself is typically built: a tiered schedule based on assets under management, assessed quarterly, deducted directly from the client's account, with the arithmetic run by billing software or a third party. That's the pattern SEC examiners found most common across roughly 130 examinations of SEC-registered investment advisers in the November 2021 risk alert ^[1].

Billing platforms are where the fee schedule, billing cadence, and household grouping actually get set. Altruist's own fee-billing page, for instance, describes configuring monthly, quarterly, or annual invoice schedules and choosing between billing each household account or billing them all to one specified account ^[2]. That configuration is still a human input — exactly where the errors below start. A tie-out checks the output against two sources that never went through that setup.

The quarterly tie-out checklist

Run this checklist once a quarter, before fee statements go final, on a sample that includes every new, terminated, and household-change account since the last billing cycle, plus a sample at a breakpoint boundary. Examiners have noted that checklists and other tools for reconciling client fee calculations against advisory agreements may be useful when applied consistently ^[1]; the steps below are one way to build that tool.

1. 01
   Pull the three inputs

   For each sampled account, pull the platform's computed fee, the custodian's fee-debit record, and the current, signed fee schedule on file.

2. 02
   Confirm the fee schedule is current

   Check the effective date the platform used against the signed agreement. A rate change, a new tier, or a client not yet converted to an updated schedule is a common source of error.

3. 03
   Check householding and aggregation

   Confirm which accounts are grouped for breakpoint purposes, and that any account excluded from (or wrongly included in) the household matches how the agreement defines it.

4. 04
   Recompute billable AUM independently

   Pull the custodian's statement balance as of the agreement's stated valuation date and compare it to the balance the platform used, confirming excluded asset types stayed excluded. Also check for a feed-timing difference in pending cash or dividends, a documented cause of valuation errors.

5. 05
   Check flow proration

   For any account with a deposit or withdrawal during the period, confirm the fee was prorated the way the agreement describes, not a default the platform applied.

6. 06
   Match the computed fee to the custodian debit

   Confirm the amount, the debit date, and the account match what the platform calculated. A mismatch isn't necessarily a calculation error: it may have posted to the household's paying account, been partial or rejected, reflect a manual override, or post across the period boundary — see the tie-out section below.

7. 07
   Trace new, terminated, and household-change accounts

   Walk every account opened, closed, or moved into or out of a household since the last cycle — easy to miss in a platform-only review.

8. 08
   Log exceptions and route for sign-off

   Record every variance in the taxonomy below, with its evidence, and get the right approver's sign-off before the quarter's fee statements are final.

What are the most common fee billing errors?

Among the fee-calculation errors SEC examiners documented were wrong or outdated fee schedules, breakpoint and tiered-rate miscalculation, householding errors, incorrect account valuations, new accounts not billed pro rata, and double-billing; the alert doesn't rank them by frequency. The SEC's Division of Examinations identified fee-related deficiencies in most of the roughly 130 examinations in its advisory fees initiative ^[1].

Specific patterns the exams turned up include fees charged at a rate different from the signed agreement, the wrong schedule applied to a client population it wasn't meant for, clients never converted to an updated schedule, and fee percentages mistyped into the portfolio management system ^[1]. Breakpoint and tiered-rate errors were usually the tiered schedule not applied correctly, or not applied at all ^[1].

Householding errors went the same way: related accounts that should have been aggregated for breakpoint purposes weren't, or the declining-rate schedule wasn't applied once they were ^[1]. Valuation errors included cases where the wrong balance fed the calculation: assets a disclosure said were excluded still counted, balances went stale across a portfolio-management-system migration, the wrong valuation date was used, or a timing difference between the custodian's feed and its available balance produced a different number ^[1].

How do you tie out custodian fee debits to calculated fees?

Tying out a custodian fee debit means confirming three things agree for each account: the dollar amount, the debit date, and the account it posted to, against what the billing platform calculated. A mismatch at this step isn't necessarily a calculation error: causes outside the calculation itself include the debit posting to the household's designated paying account, a partial or rejected debit, a manual override applied after the invoice was computed, or a posting date that falls across the period boundary.

Examiners specifically flagged account values that differed because of timing gaps in cash and dividend transactions between a custodian's electronic feed and the available balance the custodian reports — for example, a pending deposit excluded from the available balance on one side but not the other ^[1]. Rebuilding the valuation-date balance from the custodian's own statement, rather than trusting the feed the platform already ingested, is how a tie-out catches that category instead of assuming the platform is right.

• Valuation date — checked at step 4; a mismatch there is a valuation error, not a debit-match failure.
• Pending or in-transit cash (deposits or dividends not yet settled) — also checked at step 4.
• Same account, not a related account in the same household that absorbed part of the debit.
• Same fee — check for a manual override or discount applied after the platform computed the invoice.

Should fee reconciliation be separate from the billing platform?

Yes. A fee tie-out should run outside the platform that calculated the fee: checking the platform's output against itself only confirms its arithmetic is internally consistent, not that its configuration, schedule, or account values were correct in the first place.

Examiners found that advisers with centralized billing had fewer clients billed incorrectly than advisers whose billing was dispersed across separate people who each prepared and invoiced client statements, paired with validating that the fees charged to clients are consistent with advisory contracts. The same finding notes that checklists and other tools for reconciling fee calculations against client advisory agreements may be useful when used consistently ^[1]. An independent tie-out still catches a configuration error the platform can't flag on its own, since it repeats the same answer regardless.

Where to start: a first scoped workflow

Start with one quarter and one subset of accounts, not the whole book.

• Start with the accounts the checklist singles out: accounts opened or closed last quarter, household changes, and a sample at a breakpoint boundary.
• Pull the three inputs — platform fee, custodian debit, signed agreement — and run the eight-step checklist by hand before automating anything.
• Record every exception in the taxonomy, with its evidence and approver, so the categories are calibrated to your own book, not assumed.
• Automate the mechanical steps: the custodian fee-file and statement pulls, the debit-to-invoice match, and logging exceptions and routing them to the taxonomy's approver. We recommend exception approval and fee adjustments stay with the RIA's own billing and compliance staff.

When this doesn't apply

• Your billing platform already reconciles against the custodian and shows the match result — check whether that's independent of the configuration that computed the fee, not a second report from the same system.
• You bill a small number of accounts with no tiers, no householding, and no mid-period flows. Most of the categories above don't apply; a simple spot-check may be enough.
• The disagreement is about what the agreement should say, not what it does say — a question for your compliance team or counsel, not a reconciliation step.
